Here we answer the question: "What two numbers multiply to 972 and add up to 247?"

The answer to your question is:

4 and 243

Below we illustrate and prove that 4 and 243 multiply to 972 and add up to 247:

4 × 243 = 972
4 + 243 = 247

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 247x + 972 = 0

If so, the solution to factor the quadratic equation above is:

(x + 4 ) (x + 243)

To summarize, since 4 and 243 multiply to 972 and add up 247, you know that the following is true:

x² + 247x + 972 = (x + 4 ) (x + 243)
